Details

Description:
The tuner (USB Hauppauge WinTV HVR900) works OK if inserted after system restart. Unfortunately:
- suspending the notebook if the tuner is present results in system freeze when waking up (as it used to be, it's nothing new),
- disconnecting the tuner keeps the system running while causing a serious crash; the tuner is unuseable until the reboot (it changed during last max. 2 days)

Additional info:
* log file attached (the second case)

Probably linux s fault, which drivers are you using. If they are provided by linux , report upstream at bugzilla else at your driver manufacturer.

Just rolled back the kernel (to 2.6.39) and now it works fine. Something wrong with the 3.0 release; hasn't it been stabilized too quickly?

I'm using the the following (kernel) modules:

The em28xx is critical -- unloading it causes kernel panic.

I have a PCMCIA tuner in other notebook (AverTV E501R with saa7134 drivers) and experience similar crash :-(

Same with the recent one (3.0.3)

Solved by the kernel 3.2.1
